The Mismeasure of Man

A history and critique of the methods and motivations underlying biological determinism, the belief that "the social and economic differences between human groups- primarily races, classes, and sexes - arise from inherited, inborn distinctions and that society, in this sense, is an accurate reflection of biology." The book critiques the principal theme of biological determinism, the idea that "worth can be assigned to individuals and groups by measuring intelligence as a single quantity."
